SURVEYORS FLAGPOLE.

Specification of Letters Patent.

Patented Mar. 16, 1915.

Application filed February 13, 1914. Serial No. 818,535.

To all whom it may concern:

Be it known that I, WILLIAM ALBERT DAVIDSON, a subject of the King of Great Britain, and a resident of the city of Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Surveyors Flagpoles, of which the following is a specification.

My invention relates to improvements in surveyors flagpoles, and the object of my invention is to devise a flagpole which is adapted to be driven into the ground much more easily and quickly than is possible with the ordinary type of pole in present use.

A further objectis to devise a pole adapted to be driven with ease into very hard soils and thus overcome the difiiculty met with at the present time in the placing of the present type of pole in very hard ground.

A still further object is to devise a pole, Which, when in position, will not be so easily blown over by high winds, as in the case of the present type of pole, thus causing a considerable saving of time to be effected which is usually otherwise lost in looking for fallen poles.

I attain these objects by the means illustrated in the accompanying drawings in which Figure 1 is a view of the lower end of my flagpole showing the shoe attachment and side slot arrangement. Fig. 2 is a view showing the relative position of the slots in the shoe. Fig. 3 is a sectional elevation of the lower end of my flagpole, the spike member being shown in full. Fig. 4c is an outside view of the lower end of the stafi' member, showing the ferrule on the end thereof.

Similar figures of reference indicate similar parts throughout the several views.

1 is the staif member of my flagpole, which staff may be of the ordinary type in present use.

2 is a steel ferrule secured to the staff member 1 by any suitable means, such as the screws 3, and which ferrule incases the lower end of the staff member, as shown more particularly in Fig. 3.

1 is a socket of cast steel or other suitable material, formed preferably as shown in Figs. 1, 2 and 3, and adapted to slidably receive the ferrule-incased end of the stafi' member 1.

5 is a metal spike of suitable length, adapted to be secured rigidly into the lower end of the socket 1.

6 are slots formed in the walls of the socket 4t, and directly opposite to each other. The lower end of each slot is continued around the body of the socket at right angles to the main slot, as shown at 7 in Figs. 1 and 2, each such continuation being in the same direction of rotation.

8 is a pin adapted to extend from side to side of the socket 4 through the slots 6 and through the ferrule-incased end of the staff member when the complete flagpole is assembled to connect the staif member and the socket together. This pin 8 is extended beyond the walls of the socket 4L sufliciently to allow of the washers 9 and cotter pins 10 being used, as shown in Figs. 1, 2 and 3, to prevent the pin 8 from coming out after having been assembled in place. These washers 9 are so positioned that the pin 8 is free to slide up and down in the slots 4, While at the same time they prevent any side play of the pin.

11 is an opening formed through the ferrule-incased end of the staff member in proximity to the end thereof, as shown in Fig. 4:, through which opening the pin 8 is adapted to be engaged when the flagpole is assembled.

Having thus indicated the principal parts of my invention, I will now describe the manner in which it is used. My flagpole is assembled for use as shown in section in Fig. 3, that is, the ferrule-incased end of the staff member 1 is engaged slidably into the socket 4, and positioned so that the opening 11 is in alinement with the slots 6. The pin 8 is then passed through the slots 6 and the opening 11, after which the washers 9 are engaged on the ends of the pin 8 and held securely in place by means of the cotter pins 10. The flagpole is now completely assembled and ready for use.

In order to drive the flagpole into the ground it is necessary, for the first blow, that the socket 4 and staff member 1 should be held firmly together. This is accomplished by turning the staff member around in the socket so that the pin 8 will be engaged in the continuations 7 of the main slots. When this is done, the flagpole may be raised and an effective downward blow struck, driving the spike 5 into the ground. Then, to drive it still deeper, the stafl member is turned in the reverse direction, thus disengaging the pin 8 from the continuations 7' of the slots 6 and allowing the staff member to be moved up and down in the socket to deliver effective driving blows on the spike until the required depth hasbeen attained. The staff member 1 is then supported firmly in the socket 4. It will be seen, therefore, that I have devised a flagpole which is adapted to be quickly and easily driven into the ground, irrespective of the nature of: the soil, and one which is not easily blown over by high winds after hav ing been placed in position, thereby causing a considerable saving of time to be effected by its use which is otherwise lost in looking for fallen flags and at the same time providing a much more easily driven pole than the type in'use at the present time.

What I claim as my invention is 1. In a surveyors flagpole, the combination with a staff member, of a socket member the lower end of which is substantially spike shape in formation, said socket member being provided with one or more vertical bayonet slots, and means engaging said slots andsaid staff whereby the stafl' may be slidably retained inthe said socket and its disengagement therefrom prevented, said means being adapted to permit vertical reciprocatory movement of the stafl within the socket so that the spike shaped lower end of the socket may be driven into the earth at each downward movement of the staff, and means provided at the lower end of said. slots whereby the staff may be held in fixed position.

v 2. In a surveyors flagpole, the combination with a stafl' member, of a socket member the lower end ofwhich is substantially spike shape information, said socket member being provided with a pair of bayonet slots and adapted to bevslidably engaged on the said staff member, means engaging said slots and said staff whereby the staif may be moved upwardly and downwardly within the socket Without disengagement therefrom, and means for locking the staff in said socket at its lowermost position, as and for the purpose specified.-
